Abstract

FIELD: chemistry.
SUBSTANCE: present invention relates to a method for bonding a thermoplastic polymer to a thermosetting polymer component. Thermosetting polymer component includes an implant of thermoplastic polymer. Thermoplastic polymer has a melting temperature that exceeds curing temperature of thermosetting polymer. Heat is applied to melt thermoplastic polymer, to be bonded. Thermoplastic polymer of implant is located on fused interface. Implant is designed such that heating above maximum operating temperature of thermosetting polymer at interface of implant with thermosetting polymer component is avoided during bonding step. Temperature gradient is maintained due to usage of heat sinks on parts of implant, which are removed after bonding.
EFFECT: wider range of thermosetting polymers to be bonded by fusion with other thermosetting polymers or thermoplastic polymers.

Предпосылки для создания изобретенияBackground to the invention

Термопластичные (армированные волокном) полимеры, включая олигомеры, все больше используют в качестве строительного материала, поскольку последний можно перерабатывать. Термопластичный полимер может быть нагрет для его размягчения (аморфные термопласты) или для его конечного расплавления (полукристаллические термопласты) и затем охлажден, чтобы вернуть его в твердое состояние. Такие вызываемые температурой физические изменения обычно обратимы, что делает термопластичные полимеры перерабатываемыми. В твердых аморфных термопластах молекулярные цепи полимера расположены неупорядоченно, тогда как в твердых полукристаллических термопластах некоторые части включают молекулярные цепи полимера, расположенные упорядоченно: кристаллические участки. Изобретение не ограничено одним типом термопластичного полимера, даже если использована формулировка "расплавление" или "расплав". Термопластичные полимеры имеют температуру стеклования (Tg), выше которой при дальнейшем нагреве прогрессивно происходит размягчение. При температурах значительно выше температуры стеклования аморфные термопласты ведут себя как жидкость высокой вязкости, тогда как полукристаллические полимеры все еще твердые в этой области температур. Полукристаллические термопласты имеют температуру расплавления (Tm), выше которой материал плавится и ведет себя как жидкость. При дальнейшем повышении температуры вязкость быстро падает.Thermoplastic (fiber reinforced) polymers, including oligomers, are increasingly being used as a building material since the latter can be recycled. The thermoplastic polymer can be heated to soften it (amorphous thermoplastics) or to finally melt it (semi-crystalline thermoplastics) and then cooled to return it to a solid state. Such temperature-induced physical changes are usually reversible, making thermoplastic polymers recyclable. In solid amorphous thermoplastics, the polymer molecular chains are disordered, while in solid semi-crystalline thermoplastics some parts include polymer molecular chains arranged in an orderly fashion: crystalline regions. The invention is not limited to one type of thermoplastic polymer, even if the phrase “melt” or “melt” is used. Thermoplastic polymers have a glass transition temperature (Tg) above which softening progressively occurs upon further heating. At temperatures well above the glass transition temperature, amorphous thermoplastics behave like a high viscosity liquid, while semi-crystalline polymers are still solid in this temperature range. Semicrystalline thermoplastics have a melting point (Tm), above which the material melts and behaves like a liquid. With a further increase in temperature, the viscosity decreases rapidly.

Термореактивные полимеры обычно являются сшитыми полимерами, которые включают смолы, такие как эпоксид (часто называется "эпоксидная смола"), бисмалеимид, ненасыщенный полиэфир и винилэфирные полимеры. Термореактивный полимер обычно включает перед отверждением смолу (мономер) и отвердитель, которые реагируют между собой, создавая сшитый полимер. Отверждение может происходить при комнатной температуре или при более высоких температурах, которые обычно находятся в диапазоне от 80 до 200°C. Во время отверждения мономер и отвердитель реагируют друг с другом, и вязкость смеси возрастает до тех пор, пока смесь не станет сшитым твердым полимером, причем это состояние необратимо при изменении температуры, если только термореактивный полимер не разрушают при температуре выше температуры его деградации. После отверждения термореактивный полимер также имеет температуру стеклования, выше которой происходит значительное размягчение термореактивного полимера, и он проявляет характеристики резины.Thermosetting polymers are typically crosslinked polymers that include resins such as epoxy (often referred to as “epoxy resin”), bismaleimide, unsaturated polyester and vinyl ester polymers. A thermoset polymer typically includes a resin (monomer) and a hardener prior to curing, which react with each other to form a crosslinked polymer. Curing can occur at room temperature or at higher temperatures, which are usually in the range of 80 to 200 ° C. During curing, the monomer and hardener react with each other, and the viscosity of the mixture increases until the mixture becomes a crosslinked solid polymer, and this state is irreversible when the temperature changes, unless the thermoset polymer is destroyed at a temperature above its degradation temperature. After curing, the thermoset polymer also has a glass transition temperature, above which there is a significant softening of the thermoset polymer, and it exhibits rubber characteristics.

Полимерные композитные материалы включают армирующие волокна или частицы, введенные в матрицу полимера, который может быть термореактивным или термопластическим. Хорошо известные полимерные композиты включают полиэфирную смолу, армированную стекловолокном, и эпоксидную смолу, армированную углеродным волокном. Оба этих композита используют в качестве матрицы термореактивные полимеры, и поэтому их часто называют термореактивными композитами.Polymeric composite materials include reinforcing fibers or particles incorporated into a polymer matrix, which may be thermosetting or thermoplastic. Well-known polymer composites include glass fiber reinforced polyester resin and carbon fiber reinforced epoxy resin. Both of these composites use thermosetting polymers as matrices, and therefore they are often called thermosetting composites.

Одним крупным недостатком термореактивных (композитных) полимеров является то, что они обычно не поддаются сварке, поскольку термореактивный полимер не может быть расплавлен и повторно отвержден путем подъема и снижения температуры. Термореактивные (композитные) полимеры обычно соединяют с другими компонентами, используя адгезионную связь или болты, причем и то, и другое имеет свои недостатки.One major drawback of thermosetting (composite) polymers is that they are usually not weldable because the thermosetting polymer cannot be melted and re-solidified by raising and lowering the temperature. Thermosetting (composite) polymers are usually combined with other components using an adhesive bond or bolts, both of which have their drawbacks.

Адгезионная связь требует больших расходов, иногда опасна для окружающей среды, и качество полученной связи обычно чувствительно к изменениям в технологических параметрах. Соединение болтами, с другой стороны, требует отверстий в соединяемых компонентах, что вызывает концентрации напряжений и возможный преждевременный выход из строя.Adhesive bonding is expensive, sometimes dangerous for the environment, and the quality of the bond obtained is usually sensitive to changes in technological parameters. Bolting, on the other hand, requires holes in the components to be connected, which causes stress concentrations and possible premature failure.

Раскрытие изобретенияDisclosure of invention

В первом аспекте изобретение предлагает способ соединения термопластичного полимера (компонента) с компонентом из термореактивного полимера, причем термопластичный полимер имеет температуру плавления, которая превышает температуру отверждения термореактивного полимера, при этом способ включает следующие этапы: а) предоставление термопластичного полимера, b) предоставление неотвержденного или частично отвержденного компонента из термореактивного полимера, имеющего температуру отверждения ниже температуры плавления термопластичного полимера и включающего имплант из термопластичного полимера по меньшей мере в части компонента из термореактивного полимера, подлежащего соединению, с) введение термопластичного полимера в контакт по меньшей мере с деталью, подлежащей соединению, d) нагрев термопластичного полимера и компонента из термореактивного полимера до температуры плавления термопластичного полимера, в результате чего термопластичный полимер импланта расплавляется и сливается с термопластичным полимером, и в результате чего неотвержденный компонент из термореактивного полимера и термопластичный полимер импланта по меньшей мере частично проникают друг в друга; и е) охлаждение продукта соединения термопластичного полимера и отвержденного компонента из термореактивного полимера, чтобы термопластичный полимер соединился с отвержденным компонентом из термореактивного полимера, причем термопластичный полимер имеет температуру плавления, которая превышает температуру отверждения термореактивного полимера, и имплант выполнен так, что нагрев сверх максимальной рабочей температуры термореактивного полимера на поверхности раздела импланта с компонентом из термореактивного полимера исключен на этапе d) соединения.In a first aspect, the invention provides a method for bonding a thermoplastic polymer (component) with a component of a thermosetting polymer, the thermoplastic polymer having a melting point that is higher than the curing temperature of the thermosetting polymer, the method comprising the following steps: a) providing a thermoplastic polymer, b) providing an uncured or a partially cured component of a thermosetting polymer having a curing temperature below the melting temperature of thermoplastic polymer and comprising a thermoplastic polymer implant in at least a portion of the thermosetting polymer component to be joined, c) contacting the thermoplastic polymer with at least the part to be joined, d) heating the thermoplastic polymer and the thermosetting polymer component to the melting temperature thermoplastic polymer, as a result of which the thermoplastic polymer of the implant melts and coalesces with the thermoplastic polymer, and as a result, the uncured component of those the pmoreactive polymer and the thermoplastic polymer of the implant penetrate at least partially into each other; and e) cooling the product of the compound of the thermoplastic polymer and the cured component of the thermosetting polymer so that the thermoplastic polymer is combined with the cured component of the thermosetting polymer, the thermoplastic polymer having a melting point that is higher than the curing temperature of the thermosetting polymer, and the implant is designed so that the heating is above the maximum operating temperature the temperature of the thermosetting polymer on the interface between the implant and the component from the thermosetting polymer is excluded step d) compound.

Максимальная рабочая температура полимера (композитного) хорошо известна специалисту в данной области техники и обычно сообщается поставщиком. В способе согласно изобретению имплант из термопластичного полимера действует в качестве теплоотвода для компонента из термореактивного полимера (композитного), в результате чего теплота, прилагаемая для расплавления термопластичного полимера, подлежащего соединению, и импланта из термопластичного полимера, находится по существу на свариваемой поверхности раздела, где эта теплота поглощается при расплавлении импланта из термопластичного полимера. Согласно изобретению температурный градиент поддерживается в термопластичном импланте во время термического соединения сваркой, так что температура на поверхности раздела импланта с компонентом из термореактивного полимера (композитного) достаточно низкая, чтобы существенно не ухудшить свойства термореактивного полимера, даже когда температура нагрева выше температуры деградации. Это исключает чрезмерный нагрев на поверхности раздела между термореактивным полимером (композитным) и имплантом, и поэтому дает возможность соединить термопластичный полимер с компонентом из термореактивного полимера, где термопластичный полимер имеет температуру плавления, которая превышает температуру отверждения термореактивного полимера, посредством сварки.The maximum operating temperature of the polymer (composite) is well known to those skilled in the art and is usually reported by the supplier. In the method according to the invention, the thermoplastic polymer implant acts as a heat sink for the component of the thermosetting polymer (composite), whereby the heat applied to melt the thermoplastic polymer to be bonded and the thermoplastic polymer implant is located essentially on the welded interface, where this heat is absorbed when the implant is melted from a thermoplastic polymer. According to the invention, the temperature gradient is maintained in the thermoplastic implant during thermal bonding by welding, so that the temperature at the interface of the implant with the component of the thermosetting polymer (composite) is low enough not to significantly degrade the properties of the thermosetting polymer, even when the heating temperature is higher than the temperature of degradation. This eliminates excessive heating at the interface between the thermosetting polymer (composite) and the implant, and therefore makes it possible to connect the thermoplastic polymer with a component of the thermosetting polymer, where the thermoplastic polymer has a melting point that exceeds the curing temperature of the thermosetting polymer by welding.

Вышеописанное преимущество подходит, в частности, для применения в космической и авиационной промышленности, где относительно высокие температуры использования диктуют использование термопластичных полимеров с относительно высокой температурой плавления.The above advantage is suitable, in particular, for applications in the space and aviation industries, where relatively high temperatures of use dictate the use of thermoplastic polymers with a relatively high melting point.

В одном варианте осуществления изобретения предложен способ, в котором теплоемкость импланта на единицу длины в Дж/°K/м больше чем теплота, прилагаемая к продукту соединения на единицу длины во время этапа d). Другими словами, положение и размеры поперечного сечения импланта, а также термопластичный полимер импланта выбирают так, чтобы выполнить вышеуказанные требования. Теплота, прилагаемая к продукту соединения на единицу длины на этапе d), в частности теплота сварки на единицу длины также специфическая для конкретного материала и зависит от ряда факторов, таких как используемый способ сварки, удельная теплоемкость свариваемого материала, его проводимость и время, требующееся для сохранения расплавленного состояния, чтобы получить хорошо затвердевший материал после локального нагрева или сварки. Теплоту сварки на единицу длины специалист в данной области может легко определить экспериментальным путем.In one embodiment, a method is provided in which the heat capacity of the implant per unit length in J / ° K / m is greater than the heat applied to the product of the compound per unit length during step d). In other words, the position and dimensions of the cross-section of the implant, as well as the thermoplastic polymer of the implant, are chosen to fulfill the above requirements. The heat applied to the joint product per unit length in step d), in particular the heat of welding per unit length, is also specific to a particular material and depends on a number of factors, such as the welding method used, specific heat of the material being welded, its conductivity and the time required for preservation of the molten state to obtain well-hardened material after local heating or welding. The heat of welding per unit length can be easily determined experimentally by a person skilled in the art.

В еще одном варианте осуществления изобретения предложен способ, в котором теплоотводы нанесены на части импланта, более предпочтительно снаружи импланта и наиболее предпочтительно на наружные края импланта. Подходящие теплоотводы включают блоки, полосы, прутки и т.д. из материала, обычно используемого в качестве материала теплоотвода, в частности имеющего относительно высокую удельную теплоемкость. Подходящие материалы включают металлы. Поверхности раздела теплоотводов с имплантом также может быть снабжена, например, теплопоглощающей пастой. Теплоотводы удаляют после соединения.In yet another embodiment, a method is provided in which heat sinks are applied to parts of an implant, more preferably to the outside of the implant and most preferably to the outer edges of the implant. Suitable heat sinks include blocks, strips, rods, etc. from a material commonly used as a heat sink material, in particular having a relatively high specific heat. Suitable materials include metals. The interface of the heat sinks with the implant may also be provided, for example, with heat-absorbing paste. Heat sinks are removed after connection.

Импланты компонента из термореактивного полимера предпочтительно включают армирующие волокна. В еще одном варианте осуществления изобретения предложен способ, в котором имплант включает армирующие волокна, которые проходят в термореактивный полимер. Такой вариант осуществления позволяет уменьшить теплоту и/или время сварки, этим исключая деградацию термопластичного и/или термореактивного полимера во время соединения, при этом все же с получением удовлетворительной прочности соединения.The implants of the thermosetting polymer component preferably include reinforcing fibers. In yet another embodiment, a method is provided in which the implant comprises reinforcing fibers that extend into a thermosetting polymer. This embodiment allows to reduce the heat and / or welding time, thereby eliminating the degradation of the thermoplastic and / or thermosetting polymer during the connection, while still obtaining a satisfactory bond strength.

В еще одном аспекте изобретения предложен способ соединения компонента из термореактивного полимера с другим компонентом из термореактивного полимера, причем в этом способе термопластичный полимер представлен в форме отвержденного компонента из термореактивного полимера, включающего имплант из термопластичного полимера.In yet another aspect of the invention, there is provided a method of joining a component of a thermosetting polymer with another component of a thermosetting polymer, wherein in this method the thermoplastic polymer is in the form of a cured component of a thermosetting polymer comprising an implant of a thermoplastic polymer.

В еще одном аспекте изобретения предложен отвержденный компонент из термореактивного полимера, включающий имплант из термопластичного полимера по меньшей мере в части компонента из термореактивного полимера, подлежащего соединению.In yet another aspect of the invention, there is provided a cured component of a thermosetting polymer comprising an implant of a thermoplastic polymer in at least a portion of a component of a thermosetting polymer to be bonded.

В одном предпочтительном варианте осуществления первого аспекта изобретения предложен способ, в котором имплант выполнен так, что исключен чрезмерный нагрев на поверхности раздела между имплантом и компонентом из термореактивного полимера.In one preferred embodiment of the first aspect of the invention, a method is provided in which the implant is configured to prevent excessive heating at the interface between the implant and the thermosetting polymer component.

В еще одном предпочтительном варианте осуществления изобретения предложен способ, в котором компонент из термореактивного полимера включает армированный волокном компонент из термореактивного композитного полимера.In another preferred embodiment, a method is provided in which a thermosetting polymer component comprises a fiber-reinforced thermosetting composite polymer component.

Еще один предпочтительный вариант осуществления способа согласно изобретению отличается тем, что компонент из термореактивного полимера является продуктом соединения уложенных друг на друга и предварительно пропитанных лент из термореактивного композитного полимера и импланта, включающего уложенные друг на друга и предварительно пропитанные ленты из термопластичного композитного полимера. Еще один вариант осуществления способа согласно изобретению относится к способу, в котором термопластичным полимером, подлежащим соединению, является компонент из термопластичного полимера или компонент с поверхностью, совместимой с термопластичным полимером.Another preferred embodiment of the method according to the invention is characterized in that the thermosetting polymer component is the product of joining stacked and pre-impregnated thermoset composite polymer tapes and an implant, including thermoplastic composite polymer tapes stacked on top of each other. Another embodiment of the method according to the invention relates to a method in which the thermoplastic polymer to be bonded is a component of a thermoplastic polymer or a component with a surface compatible with the thermoplastic polymer.

Еще один предпочтительный вариант осуществления способа согласно изобретению предлагает использование термопластичного полимера, подлежащего соединению, и/или импланта из термопластичного полимера, который выбирают из класса технических термопластичных полимеров, имеющих температуру плавления по меньшей мере 200°C. В одном даже более предпочтительном способе термопластичный полимер, подлежащий соединению, и/или имплант из термопластичного полимера выбирают из полиэфиримида (PEI), полиэфирэфиркетона (PEEK), полифениленсульфида (PPS), полиэфиркетона (PEK), полиэфиркетонкетона (PEKK) и их сочетаний или эквивалентов.Another preferred embodiment of the method according to the invention provides the use of a thermoplastic polymer to be bonded and / or an implant of a thermoplastic polymer selected from the class of technical thermoplastic polymers having a melting point of at least 200 ° C. In one even more preferred method, the thermoplastic polymer to be bonded and / or the thermoplastic polymer implant is selected from polyetherimide (PEI), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), polyether ketone (PEK), polyether ketone ketone (PEKK) and combinations thereof or .

Еще один вариант осуществления способа в соответствии с изобретением отличается тем, что термопластичный полимер, подлежащий соединению, или имплант из термопластичного полимера включает электропроводящие частицы для локализованного нагрева.Another embodiment of the method in accordance with the invention is characterized in that the thermoplastic polymer to be joined or an implant of a thermoplastic polymer includes electrically conductive particles for localized heating.

В одном варианте осуществления способа согласно изобретению термореактивный полимер включает эпоксидную смолу и/или смесь бисмалеимидной смолы/отвердителя.In one embodiment of the method of the invention, the thermosetting polymer comprises an epoxy resin and / or a bismaleimide resin / hardener mixture.

Неотвержденный или частично отвержденный компонент из термореактивного полимера, имеющий имплант из термопластичного полимера, который формирует способную к соединению поверхность, может быть легко изготовлен путем наложения предварительно пропитанных лент из термореактивного композитного полимера друг на друга и наложения предварительно пропитанных лент из термопластичного композитного полимера друг на друга для формирования импланта. Термопластичные импланты могут также быть изготовлены на месте с использованием способов инжекции. Также возможна совместная инжекция термореактивных и термопластичных полимеров.An uncured or partially cured thermosetting polymer component having an implant of a thermoplastic polymer that forms a bonding surface can be easily made by applying pre-impregnated thermoset composite polymer tapes to each other and applying pre-impregnated thermoplastic composite polymer tapes to each other to form an implant. Thermoplastic implants can also be made locally using injection methods. Joint injection of thermoset and thermoplastic polymers is also possible.

Компонент из термореактивного полимера, включающий имплант, предпочтительно соединяют с термопластичным полимером (компонентом) или с другим компонентом из термореактивного полимера, включающим имплант, посредством сварки с другим термореактивным полимером, или термореактивным композитным полимером, или с термопластичным полимером (композитным).A thermosetting polymer component comprising an implant is preferably combined with a thermoplastic polymer (component) or another thermosetting polymer component including an implant by welding with another thermosetting polymer or thermosetting composite polymer or with a thermoplastic polymer (composite).

Предпочтительные способы сварки включают индукционную сварку, сварку сопротивлением и лазерную сварку, но без ограничения этими способами.Preferred welding methods include, but are not limited to, induction welding, resistance welding, and laser welding.

В еще одном аспекте изобретения предложен продукт соединения отвержденного компонента из термореактивного полимера с термопластичной поверхностью и компонента из термопластичного полимера, приваренного к нему, причем термопластичный полимер имеет температуру плавления, которая превышает температуру отверждения термореактивного полимера.In yet another aspect of the invention, there is provided a product for joining a cured component of a thermosetting polymer with a thermoplastic surface and a component of a thermoplastic polymer welded to it, the thermoplastic polymer having a melting point that exceeds the curing temperature of the thermosetting polymer.

В любом из вышеприведенных вариантов осуществления изобретения имплант из термопластичного полимера и неотвержденный термореактивный полимер или термореактивный композитный полимер, который примыкает к импланту, способны при нагреве по меньшей мере частично проникать друг в друга перед отверждением термореактивного полимера, этим соединяя имплант из термопластичного полимера с термореактивным полимером или термореактивным композитным полимером. Это гарантирует, что термопластичная поверхность импланта, соединяемая с термореактивным полимером (композитным), не может быть легко удалена с термореактивного полимера или термореактивного композитного полимера.In any of the above embodiments, the thermoplastic polymer implant and the uncured thermoset polymer or thermoset composite polymer that is adjacent to the implant are capable of penetrating at least partially into each other when the thermoset polymer is cured, thereby combining the thermoplastic polymer implant with the thermoset polymer or a thermoset composite polymer. This ensures that the thermoplastic surface of the implant connected to the thermosetting polymer (composite) cannot be easily removed from the thermosetting polymer or thermosetting composite polymer.

Отвержденный или неотвержденный термореактивный полимер или термореактивный композитный полимер с термопластичным имплантом может быть соединен с другим термопластичным полимером в соответствии со способом изобретения или может быть соединен с вторым термореактивным полимером или термореактивным композитным полимером, снабженным термопластичным имплантом.The cured or uncured thermosetting polymer or thermosetting composite polymer with a thermoplastic implant can be connected to another thermoplastic polymer in accordance with the method of the invention or can be connected to a second thermosetting polymer or thermosetting composite polymer equipped with a thermoplastic implant.

Еще одно преимущество способа изобретения заключается в том, что расплавленный термопластичный полимер, подлежащий соединению, и имплант из термопластичного полимера обеспечивают сильный поток термопластичного полимера при введении в контакт друг с другом, в результате этого заполняя любые неровности или изъяны в контактируемых поверхностях, подлежащих соединению. На термопластичный поток можно влиять путем изменения температуры и/или путем приложения повышенного давления контакта к компонентам, подлежащим соединению, во время нагрева или путем отведения дополнительного времени для соединения.Another advantage of the method of the invention is that the molten thermoplastic polymer to be bonded and the implant of the thermoplastic polymer provide a strong flow of the thermoplastic polymer when brought into contact with each other, as a result filling any irregularities or imperfections in the contact surfaces to be bonded. The thermoplastic flow can be influenced by changing the temperature and / or by applying an increased contact pressure to the components to be connected during heating or by taking extra time for the connection.

Преимущество способа изобретения, кроме того, относится к тому факту, что компоненты, которые ранее были соединены друг с другом, могут быть разобраны и повторно собраны снова при необходимости просто путем повторного нагрева, по меньшей мере частичного, сваренных термопластичного компонента и термопластичного импланта. По желанию, дополнительный термопластичный полимер может быть добавлен между поверхностями, подлежащими соединению, для получения улучшенного соединения. Повторный нагрев также можно использовать для улучшения качества получаемого сварного шва, при необходимости в выбранных областях.An advantage of the method of the invention also relates to the fact that components that were previously connected to each other can be disassembled and reassembled again if necessary simply by reheating at least partially the welded thermoplastic component and the thermoplastic implant. Optionally, an additional thermoplastic polymer may be added between the surfaces to be bonded to provide an improved bonding. Reheating can also be used to improve the quality of the resulting weld, if necessary in selected areas.

Говоря в общем, способ согласно изобретению будет осуществляться при температуре выше температуры стеклования отвержденного термореактивного полимера или компонента из композитного полимера, по меньшей мере на поверхности раздела между имплантом из термопластичного полимера и термореактивным полимером. Однако соединение может быть осуществлено при температуре, которая только немного выше, чем эта температура, или даже может быть близкой к температуре деградации термореактивного полимера.Generally speaking, the method according to the invention will be carried out at a temperature above the glass transition temperature of the cured thermosetting polymer or component of the composite polymer, at least at the interface between the thermoplastic polymer implant and the thermosetting polymer. However, the connection can be carried out at a temperature that is only slightly higher than this temperature, or may even be close to the degradation temperature of the thermosetting polymer.

Компонент из термореактивного полимера (композитного) может включать другие компоненты, такие как металлические вставки, вспененную или сотовую сердцевину, термопластичные или термореактивные компоненты или пленки, соединенные с ним другими способами, чем способ согласно изобретению, или любой другой материал, который может быть включен как неотъемлемая часть в компонент из термореактивного композита.A component of a thermosetting polymer (composite) may include other components, such as metal inserts, a foam or honeycomb core, thermoplastic or thermosetting components or films bonded to it in other ways than the method according to the invention, or any other material that may be included as integral part of a component from a thermoset composite.

Со ссылкой на Фиг. 1, на которой показан вариант осуществления продукта 1 соединения отвержденного компонента 2 из термореактивного полимера с термопластичной поверхностью 3, к которой компонент из термопластичного полимера 4 может быть приварен в соответствии со способом изобретения. Термопластичный полимер компонента 4 из термопластичного полимера имеет температуру плавления от 250°C до 400°C, которая превышает температуру отверждения термореактивного полимера, использованного в компоненте 2 из термореактивного полимера, температура отверждения которого обычно находится в диапазоне от комнатной температуры до 200°C. Продукт 1 соединения получен способом, который включает предоставление неотвержденного или частично отвержденного термореактивного полимера (прекурсора отвержденного компонента 2) с имплантом 5 из термопластичного полимера по меньшей мере на части компонента из термореактивного полимера, подлежащего соединению, который представляет собой поверхность 3 в данном случае, и отверждение термореактивного полимера, в результате чего неотвержденный компонент 2 из термореактивного полимера и имплант 5 из термопластичного полимера по меньшей мере частично проникают друг в друга. В ходе этого процесса образуется соединение между имплантом 5 из термопластичного полимера и отвержденным термореактивным полимером 2. Из-за повышенной температуры отверждения термореактивные мономеры могут фактически быстрее мигрировать через имплант 5 из термопластичного полимера, в частности через его кристаллические домены. Таким образом между ними формируется прочное соединение. Очевидно, что температура отверждения и время цикла предпочтительно выбирать так, чтобы термореактивные мономеры (и отвердитель) были способны мигрировать достаточно глубоко в расплавленный полимер импланта 5. Оснащение термореактивного полимера 2 термопластичным имплантом 5 может быть выполнено без изменения рекомендованного изготовителем цикла отверждения термореактивного полимера 2. Однако может потребоваться небольшое изменение, в частности, когда совместимость между термореактивным полимером 2 и термопластичным полимером импланта 5 не оптимальная.With reference to FIG. 1, which shows an embodiment of a product 1 of joining a cured component 2 of a thermosetting polymer with a thermoplastic surface 3, to which a component of thermoplastic polymer 4 can be welded in accordance with the method of the invention. The thermoplastic polymer of component 4 of the thermoplastic polymer has a melting point of 250 ° C to 400 ° C, which is higher than the curing temperature of the thermosetting polymer used in component 2 of the thermosetting polymer, the curing temperature of which is usually in the range from room temperature to 200 ° C. The compound product 1 is obtained by a method that includes providing an uncured or partially cured thermosetting polymer (precursor of cured component 2) with an implant 5 of a thermoplastic polymer on at least a portion of the thermosetting polymer component to be joined, which is surface 3 in this case, and curing the thermosetting polymer, resulting in an uncured component 2 of a thermosetting polymer and an implant 5 of a thermoplastic polymer at least Leray partly penetrate into each other. During this process, a connection is formed between the thermoplastic polymer implant 5 and the cured thermosetting polymer 2. Due to the increased curing temperature, thermosetting monomers can actually migrate faster through the thermoplastic polymer implant 5, in particular through its crystalline domains. Thus, a strong connection is formed between them. Obviously, the curing temperature and the cycle time are preferably chosen so that the thermosetting monomers (and hardener) are able to migrate deep enough into the molten polymer of the implant 5. Equipping the thermosetting polymer 2 with a thermoplastic implant 5 can be performed without changing the manufacturer's recommended curing cycle of thermosetting polymer 2. However, a slight change may be required, in particular when the compatibility between thermosetting polymer 2 and thermoplastic polymer impl 5-coagulant is not optimal.

Согласно изобретению, термопластичный полимер (компонент) 4 вводят в контакт по меньшей мере с поверхностью 3 продукта 1 соединения и термопластичный полимер и компонент из термореактивного полимера нагревают до температуры плавления термопластичного полимера 4, в результате чего имплант 5 из термопластичного полимера плавится и сливается с термопластичным полимером (компонентом) 4, другими словами, формирует соединение между имплантом 5 из термопластичного полимера и термопластичным полимером (компонентом) 4, которое затвердевает после охлаждения продукта 1 соединения термопластичного полимера 5 и отвержденного компонента 2 из термореактивного полимера.According to the invention, the thermoplastic polymer (component) 4 is brought into contact with at least the surface 3 of the compound product 1, and the thermoplastic polymer and the thermosetting polymer component are heated to the melting temperature of the thermoplastic polymer 4, as a result of which the thermoplastic polymer implant 5 melts and merges with the thermoplastic polymer (component) 4, in other words, forms a connection between the thermoplastic polymer implant 5 and thermoplastic polymer (component) 4, which hardens after cooling the product 1 of the compound of the thermoplastic polymer 5 and the cured component 2 of the thermosetting polymer.

Для того чтобы избежать чрезмерного нагрева термореактивного полимера в процессе выполнения соединения, зона сварки должна быть выбрана в соответствии с геометрией термопластичного импланта 5. На Фиг. 1 область сварки схематически показана как область 6. Нагрев в этой области 6 может быть выполнен при температуре плавления одного или обоих термопластичных полимеров 4 и 5. Эти полимеры 4 и 5 предпочтительно имеют температуру плавления, которая отличается только на 20°C, более предпочтительно на 15°C и наиболее предпочтительно только на 10°C. Предпочтительно, термопластичные полимеры 4 и 5 по существу являются одним и тем же полимером. Имплант 5 из термопластичного полимера соединяют с внутренней поверхностью (как в Примере, показанном на Фиг. 1) или с наружной поверхностью (как в Примере, показанном на Фиг.2) термореактивного полимера 2 во время отверждения термореактивного полимера 2, предпочтительно путем формирования сети полувзаимопроникающих полимеров. В этой связи, термопластичный полимер 5 предпочтительно совместим с выбранными термореактивными мономерами термореактивного полимера 2. Специалист в области полимеров имеет в своем распоряжении достаточно средств, таких как хорошо известные критерии термодинамики и растворимости.In order to avoid excessive heating of the thermosetting polymer during the connection, the welding zone should be selected in accordance with the geometry of the thermoplastic implant 5. In FIG. 1, the welding region is schematically shown as region 6. Heating in this region 6 can be performed at the melting temperature of one or both thermoplastic polymers 4 and 5. These polymers 4 and 5 preferably have a melting point that differs by only 20 ° C, more preferably 15 ° C and most preferably only 10 ° C. Preferably, the thermoplastic polymers 4 and 5 are essentially the same polymer. The thermoplastic polymer implant 5 is connected to the inner surface (as in the Example shown in FIG. 1) or to the outer surface (as in the Example shown in FIG. 2) of the thermosetting polymer 2 during the curing of the thermosetting polymer 2, preferably by forming a network of semi-interpenetrating polymers. In this regard, the thermoplastic polymer 5 is preferably compatible with the selected thermosetting monomers of the thermosetting polymer 2. The specialist in the field of polymers has at its disposal sufficient means, such as the well-known criteria of thermodynamics and solubility.

Обычно прочность соединения, получаемого с использованием способа согласно изобретению, превышает 30 МПа, более предпочтительно превышает 35 МПа и наиболее предпочтительно превышает 40 МПа (проверка прочности шва внахлестку).Typically, the strength of the joint obtained using the method according to the invention is greater than 30 MPa, more preferably greater than 35 MPa and most preferably greater than 40 MPa (lap weld strength test).

Типичные давления сварки составляют от 50 кПа до 1 МПа, при предпочтительном диапазоне от 100 кПа до 350 кПа. Однако способ согласно изобретению также может давать хорошие соединения без приложения давления, но также можно использовать давления, превышающие 1 МПа, хотя такие давления могут привести к некоторому выдавливанию расплавленного термопласта.Typical welding pressures range from 50 kPa to 1 MPa, with a preferred range from 100 kPa to 350 kPa. However, the method according to the invention can also produce good compounds without applying pressure, but pressures in excess of 1 MPa can also be used, although such pressures can lead to some extrusion of the molten thermoplastic.

Еще один вариант осуществления продукта 1 соединения отвержденного компонента 2 из термореактивного полимера с термопластичной поверхностью 3, к которому может быть приварен компонент 4 из термопластичного полимера 4 в соответствии со способом изобретения, показан на Фиг. 2. В этом случае имплант 5 из термопластичного полимера 5 фактически соединен с наружной поверхностью компонента 2 из термореактивного полимера. Все же его функция также соответствует изобретению, поскольку имплант 5 имеет такие размеры, что при ограничении области сварки областью 6 чрезмерный нагрев термореактивного полимера на поверхности раздела с имплантом 5 исключен.Another embodiment of the product 1 of joining a cured component 2 of a thermosetting polymer with a thermoplastic surface 3 to which a component 4 of thermoplastic polymer 4 can be welded in accordance with the method of the invention is shown in FIG. 2. In this case, the implant 5 of the thermoplastic polymer 5 is actually connected to the outer surface of the component 2 of the thermosetting polymer. Nevertheless, its function also corresponds to the invention, since the implant 5 has such dimensions that when the welding region is limited to region 6, excessive heating of the thermosetting polymer at the interface with the implant 5 is excluded.

Термореактивный полимер 2, снабженный имплантом 5 из термопластичного полимера 5, может быть соединен с термопластичным компонентом 4 посредством приложения внешней теплоты и давления, например, нагретой пластины. Альтернативно можно использовать локальный нагревательный элемент или даже нагреваемые материалы, включенные в компоненты, подлежащие соединению, позволяющие фокусировать теплоту в области 6 сварки.Thermosetting polymer 2, equipped with an implant 5 of thermoplastic polymer 5, can be connected to the thermoplastic component 4 by applying external heat and pressure, for example, a heated plate. Alternatively, you can use a local heating element or even heated materials included in the components to be connected, allowing the heat to be focused in the welding region 6.

Поскольку в способе согласно изобретению нагрев осуществляют до температуры выше температуры плавления термопластичных полимеров 4 и 5, эти термопласты будут создавать значительный поток во время сварки даже при относительно низких давлениях сварки. Этот поток позволяет термопластам 4 и 5 заполнять небольшие неровности в их поверхностях или даже относительно небольшие зазоры между свариваемыми компонентами 2 и 4.Since in the method according to the invention the heating is carried out to a temperature above the melting temperature of thermoplastic polymers 4 and 5, these thermoplastics will create a significant flow during welding even at relatively low welding pressures. This flow allows thermoplastics 4 and 5 to fill in small irregularities in their surfaces or even relatively small gaps between the components 2 and 4 to be welded.

Еще один вариант осуществления продукта 1 соединения отвержденного компонента 2 из термореактивного полимера с термопластичной поверхностью 3, к которому может быть приварен компонент 4 из термопластичного полимера 4 в соответствии со способом изобретения, показан на Фиг. 3. В этом случае имплант 5 из термопластичного полимера 5 снабжен двумя теплоотводами 10 и 11, расположенными на его наружных краях. Имплант 5 имеет такие размеры, что при ограничении области сварки областью 6 нагрев термореактивного полимера 2 на поверхности раздела 7 с имплантом 5 ограничен так, что максимальная рабочая температура термореактивного полимера не может быть превышена. Теплоотводы 10 и 11 поглощают часть теплоты сварки. Теплоотводы 10 и 11 созданы на импланте 5 путем использования слоев теплопоглощающей пасты 8. Термореактивный полимер 2, снабженный имплантом 5 из термопластичного полимера 5, соединяют с термопластичным компонентом 4, используя сварочную горелку 9, которую вводят в контакт со свариваемой частью 4 в области 6 контакта.Another embodiment of the product 1 of joining a cured component 2 of a thermosetting polymer with a thermoplastic surface 3 to which a component 4 of thermoplastic polymer 4 can be welded in accordance with the method of the invention is shown in FIG. 3. In this case, the implant 5 of the thermoplastic polymer 5 is equipped with two heat sinks 10 and 11 located on its outer edges. The implant 5 has such dimensions that when the welding region is limited to region 6, the heating of the thermosetting polymer 2 at the interface 7 with the implant 5 is limited so that the maximum operating temperature of the thermosetting polymer cannot be exceeded. Heat sinks 10 and 11 absorb part of the heat of welding. Heat sinks 10 and 11 are created on the implant 5 by using layers of heat-absorbing paste 8. The thermosetting polymer 2, equipped with an implant 5 of thermoplastic polymer 5, is connected to the thermoplastic component 4 using a welding torch 9, which is brought into contact with the welded part 4 in the contact area 6 .

В заключение, на Фиг. 4 схематически показан вид сбоку предпочтительного импланта для использования в способе изобретения. В показанном варианте осуществления использован имплант из термопластичного полимера, включающий непрерывные армирующие волокна 12, которые проходят дальше границ (50, 51) импланта 5. При затвердевании такого импланта вместе с компонентом из термореактивного полимера свободные (сухие) части волокон 12 будут заходить в термореактивный полимер, где эти части волокон будут смочены термореактивным полимером и станут одним целым с компонентом из термореактивного полимера после отверждения. Оказалось так, что имплант согласно этому варианту осуществления особенно подходит для использования в способе изобретения, поскольку он позволяет получать удовлетворительную прочность соединений, при этом ограничивая теплоту, прилагаемую во время выполнения соединения.In conclusion, in FIG. 4 is a schematic side view of a preferred implant for use in the method of the invention. In the shown embodiment, a thermoplastic polymer implant was used, including continuous reinforcing fibers 12 that extend beyond the boundaries (50, 51) of implant 5. When this implant hardens, together with the thermosetting polymer component, the free (dry) parts of the fibers 12 will enter the thermosetting polymer where these parts of the fibers will be moistened with a thermosetting polymer and will become one with the component of the thermosetting polymer after curing. It turned out that the implant according to this variant implementation is particularly suitable for use in the method of the invention, since it allows you to obtain a satisfactory strength of the joints, while limiting the heat applied during the connection.

Способ согласно изобретению, кроме того, позволяет удалять сварной шов и разделять ранее сваренные компоненты 2 и 4. Для этого компоненты (2, 4) нагревают до температуры выше температуры плавления термопластичных полимеров (4, 5) и оба компонента (2, 4) разделяют по меньшей мере частично, что требует ограниченного усилия. Поскольку каждый компонент (2, 4) в сущности сохраняет большинство из своих свойств поверхности, разделенные компоненты могут впоследствии быть снова сварены в соответствии со способом изобретения. По желанию, между соединяемыми термопластичными поверхностями можно добавить дополнительный термопластичный материал, если для хорошего соединения термопластичного материала будет недостаточно.The method according to the invention, in addition, allows you to remove the weld and separate previously welded components 2 and 4. For this, components (2, 4) are heated to a temperature above the melting temperature of thermoplastic polymers (4, 5) and both components (2, 4) are separated at least partially, which requires limited effort. Since each component (2, 4) essentially retains most of its surface properties, the separated components can subsequently be welded again in accordance with the method of the invention. Optionally, additional thermoplastic material can be added between the thermoplastic surfaces to be joined if thermoplastic material is not sufficient for a good bond.

Продукт 1 соединения 1 согласно изобретению может обладать и другими преимуществами, такими как повышенная химическая стойкость, повышенная стойкость к износу и эрозии, повышенная биосовместимость, улучшенные свойства трения и т.д.The product 1 of compound 1 according to the invention may also have other advantages, such as increased chemical resistance, increased wear and erosion resistance, increased biocompatibility, improved friction properties, etc.

При этом понимается, что изобретение, раскрытое в подробном описании, приведено только для примера, и что специалист в данной области может предусмотреть многие изменения в рамках объема прилагаемой формулы изобретения.It is understood that the invention disclosed in the detailed description is by way of example only and that one skilled in the art can envision many changes within the scope of the appended claims.
